Description

Abfederung für Schwinghebel von Brennkraftmaschinen. Bei Brennkraftmaschinen, insbesondere bei Sternmaschinen, erfolgt die Steuerung der Ventile im allgemeinen unter Vermittlung von Nockenwellen, Stoßstangen und Schwinghebeln. Die Rückführung der Steuerungsteile wird durch die Ventilfeder bewirkt. Zur Dämpfung der dabei auftretenden unangenehmen Geräusche sowie zur Entlastung der Ventilfeder.hat man bereits vorgeschlagen, für die Rückführung von Schwinghebel und Stoßstange eine besondere Rückzugfedier anzuordnen.Suspension for rocker arms of internal combustion engines. In internal combustion engines, in star machines in particular, the valves are generally controlled with the mediation of camshafts, bumpers and rocker arms. The repatriation the control parts is effected by the valve spring. To dampen the occurring unpleasant noises as well as to relieve the valve spring. it has already been proposed a special retraction spring for the return of the rocker arm and bumper to arrange.

Nach der Erfindung wird diese Feder als Blattfeder ausgebildet, die auf einer festen Achse drehbar befestigt ist und sich auf einem ebenfalls federnden Bügel abwälzt. Der Bügel kann an derselben Achse angelenkt sein und stützt sich in diesem Falle auf den Boden des Gehäuses. Rückzugfeder und Bügel können auch aus einem Stück hergestellt sein.According to the invention, this spring is designed as a leaf spring, the is rotatably mounted on a fixed axis and is also resilient Hanger rolls off. The bracket can be articulated on the same axis and is supported in this case on the bottom of the housing. Retraction spring and bracket can also be made from be made in one piece.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Feder r ist gemeinsam mit dem Bügel 2 an der Achse 3 angelenkt. Der Bügel stützt sich mit seinem Ende q. auf den Boden des Gehäuses 5. Bei eintretender Durchbiegung legt sich die Feder i mehr und mehr auf den Bügel 2 auf, wodurch der federnde Teil kürzer wird. Während nun anfänglich infolge der großen Länge der Feder die Abfederung sehr weich ist, würde sie bei festem Bügel mit zunehmender Verkürzung härter und die Feder übermäßig beansprucht werden. Durch die Anordnung des ebenfalls federnden Bügels 2 wird die Feder selbst entlastet und auch in stark durchgebogenem Zustand eine gute Abfederung erzielt. Ein weiterer Vorteil der Erfindung ist der, daß die Feder an einer einfachen runden Achse befestigt und daher leicht ausgewechselt werden kann. Werden Feder und Bügel an der gleichen Achse angelenkt, so sichern sie sich außerdem gegenseitig gegen Verdrehen.In the figure, an embodiment of the invention is shown. The spring r is articulated together with the bracket 2 on the axis 3. The bracket supports with its end q. on the bottom of the housing 5. If there is a deflection the spring i rests more and more on the bracket 2, whereby the resilient part gets shorter. While now initially due to the great length of the spring, the cushioning is very soft, with a firm temple it would become harder with increasing shortening and the spring will be excessively stressed. Due to the arrangement of the also resilient Bracket 2, the spring itself is relieved and also in a strongly bent state achieved a good cushioning. Another advantage of the invention is that the The spring is attached to a simple round axle and can therefore be easily replaced can. If the spring and bracket are linked to the same axle, they are secured also mutually against twisting.
